  • Belatacept received FDA approval in November 2011 for prevention of acute kidney transplant rejection showing equivalent efficacy to existing treatments and, as a result of the mutations, greatly reduced side effects and toxicity.
  • Belatacept possesses only a two-fold increase in avidity for the B7 ligands, but exhibits a ten-fold enhancement in its biological potency [26, 53].
  • Such findings strongly support a continued role for structural and biochemical analysis of the primary co-stimulatory molecules and their cognate complexes in order to gain molecular insight that supports the development of novel therapeutic agents.
  • the disclosed technologies offer numerous advantages over existing methods: 1) expression in cell microarray format allows for the systematic expression of all classes of proteins (including multi-span integral membrane proteins such as GPCRs and transporters, as well as multicomponent receptors such as integrins); 2) cell microarray expression is highly tractable, as only DNA (i.e., expression vectors) are required, and not the purified proteins themselves; 3) the technologies are all based on the detection of direct physical interactions, and thus do not require any knowledge of biological function; 4) the flow cytometry-based method allows both the bait and the prey to be expressed on the surfaces of independent and distinguishable cells, thus removing all requirements for purified protein; and 5) the implementation of magnetic separations coupled with deep sequencing and a barcoded library of secreted protein-expressing cells offers massively parallel interrogation of many (all) ligands against
  • Cell microarray technology is adapted to systematically screen a pan-genomic library of cell surface receptors (i.e., the Secretome) against single query ligands.
  • This approach presents large numbers of receptors in the context of live host cells in a precisely arrayed format.
  • cellular microarray technology [68, 69] has been successfully adapted.
  • Each expression construct e.g., plasmid based on the pEGFP-N1 backbone and other fluorescent variants, which drive expression via the CMV promoter
  • Mammalian cells when plated over the printed cDNAs in the presence of transfection reagent (e.g., lipid-based reagent), become transfected, resulting in a living cell array, with each individual cluster expressing a distinct member of the library ( Figure 3 ). (Cells growing between the printed cDNAs are not transfected and remain "black”.) These expression arrays are then challenged with purified fluorescently-tagged query proteins. Positive interactions are scored as a function of fluorescence after washing to remove unbound ligand. As each construct is "pinned” at a known position in the microarray, a positive "hit” can immediately be correlated with its interacting partner.
  • transfection reagent e.g., lipid-based reagent
  • the cell microarray platform was validated using the PD-1:PD-L1 interaction (Kd ⁇ 5.5 ⁇ M).
  • a live cell microarray was generated consisting of alternating rows of cells expressing either a GFP fusion of PD-L1 or GFP alone ( Figure 4A ).
  • the GFP control is expressed in the cytoplasm (solid green circle), while the GFP fused to PD-L1 (green ring) is membrane localized (the lower absolute GFP fluorescence observed for the PD-L1-GFP is due to the higher expression level of the cytoplasmic GFP construct).
  • the 14 members of the nectin/nectin-like family belonging to the Ig Superfamily (IgSF) are similarly investigated. At least 10 of these proteins exhibit homophilic interactions and there are at least 20 heterophilic interactions between members of the nectin family [70-72]. Also the ⁇ 500 ectodomains and secreted proteins that comprise the entire human IgSF are run through this system. In these experiments, expression vectors for each member of the IgSF are printed to generate the microarray (i.e., each spot represents a single member of the IgSF), which is probed with Ig fusion constructs of specific IgSF members. As the majority of IgSF members bind other members of the IgSF, this affords exciting opportunities to define new receptor:ligand interactions within the IgSF.
  • IgSF members B7-H4[73-80], VISTA[81], B7-H3[74, 79, 82-85], LAG-3[86-90] and the 10 members of the butyrophilin family[91-94] are also warranted.
  • Other members of the IgSF including other members of the extended B7, Carcinoembryonic antigen-related cell adhesion molecule (CEACAM)[95] and leukocyte receptor complex[96] families, are candidate targets.

  • the expression reagents for a significant fraction of the IgSF have been successfully generated and validated ( Figure 6 ).
  • TNF and TNFR superfamilies can be part of the platform; all of these proteins are important mechanistic and therapeutic targets and are type-II membrane proteins (i.e., TNF superfamily members).
  • the technology can be applied to the entire Secretome, including GPCRs, Toll-like receptors, growth factor receptors, interleukins, interleukin receptors, ion channels, etc.
  • LIC Ligation Independent Cloning
  • LIC cloning has supported the generation of > 15,000 sequence-verified constructs over the past 18 months for large-scale structural (nysgrc.org) and functional genomics (enzymefunction.org) programs.
  • the method is aided by automated liquid handling robots, for example, a Biomek FxP liquid handler and a Perkin-Elmer EP3 robot, for the high-throughput molecular biology needed to rapidly generate the above library. All of the required expression vectors are readily generated ( Figure 6 ).
  • FIG. 12 shows a number of mutant PD-L1 Ig-fusion constructs that have recently been generated. This platform is based on the Daedelus system [98] and has the capacity to generate 48 lentiviruses per week. Furthermore, myriad secreted proteins and ectodomains have been effectively generated used as soluble Ig-fusion proteins for mechanistic studies [21-23] and therapeutic applications [24-27]. This enormous literature demonstrates that covalent fusion to non-native domains does not have a deleterious effect and is compatible with a wide range of secreted proteins and ectodomains.
  • GFP-fusions Natural integral membrane proteins will utilize native transmembrane elements to avoid the issue of differentiating between Type I and Type II integral membrane proteins in the context of cell microarray screening. Importantly, numerous examples of biologically relevant fluorescent protein-fusions (e.g., GFP-fusions) have been reported, including members of the Ig, TNF/TNFR[1-3], GPCR[4-6], integrin[7] and transporter[8] superfamilies. For cell microarrays, secreted proteins can be effectively engineered into integral membrane proteins through the addition of a transmembrane helix that anchors them to the cell surface for subsequent probing.
  • Some receptors require multiple components in order to exhibit binding activity to their cognate ligands (e.g., T cell receptor, integrins). As appropriate, these more complicated receptors are addressed by co-expressing multiple components at a single position of the cell microarray ( Figure 7 ).
  • Cell line selected for microarray presentation Cell microarray technology has been firmly established with HEK293 cells. For distinguishing those query proteins that bind to cell surface proteins that are endogenously expressed by the HEK293 cells, binding to the untransfected control cells present in all microarrays (i.e., those cells not receiving an expression vector coding for a plasma membrane localized protein) serves as a convenient control. However, in most cases the saturating levels of over-expression driven by the strong CMV promoter will dominate the low endogenous levels of cell surface expression. Moreover, appropriate statistical methods can identify statistically signal binding events. To aid in these statistical analyses, all expression vectors can be printed in duplicate in the cell microarray.
  • Drosophila S2 cells have been utilized by Sabatini for genome-scale loss-of-function studies in microarray format [99, 100].
  • suspension-adapted mammalian cell lines with decreased adherence properties i.e., HEK293 Freestyle (Invitrogen) [101]
  • HEK293 Freestyle Invitrogen
  • the mCherry (red) suspension cells are then be used to challenge the immobilized green "receptor" cells on the array.
  • Co-localized cell spots containing both GFP (e.g., microarray localized receptors) and mCherry (e.g., suspension query ligands) would result in a positive score.

  • This stable cell line specifically binds non-cell permeable Alexa 594 labeled biotin and this strategy can be used to either anchor cells to the array globally, if more rigorous washing steps are desired, or can be used to specifically tether cells to defined areas via site specific printing of biotin conjugates. Both scenarios will reduce the background signal.
  • microbead-based approach is demonstrated with the same PD-1:PD-L1 interaction described above, and expanded by including the PD-L1:B7-1 interaction.
  • Figure 8 shows the overall strategy of the microbead experiment.
  • Figure 9 shows the highly specific interactions between microbeads loaded with either PD-1 or B7-1 Ig-fusion proteins, and HEK293 cells expressing plasma membrane localized PD-L1:mCherry fusion proteins.
  • the cell-cell approach also demonstrated interactions between PD-L1-mCherry and B7-1-GFP from transiently transfected HEK293 cells (data not shown).
  • This approach appears to be of general utility as it also clearly revealed the expected interaction between CD200 and CD200-Receptor (CD200R) ( Figure 11 ), which are unrelated to the PD-1, PD-L1, B7-1 protein families.
  • Dissection of biochemical function The microbead-cell and cell-cell interactions can be used to dissect complex biochemical function by screening large numbers of mutant molecules. These capabilities have been demonstrated by generating PD-L1 point mutants that exhibit a wide range of affinities for PD-1 and B7-1, and of particular importance PD-L1 point mutants that exclusively bind to either PD-1 or B7-1. These studies used the generation of HEK293 cell lines individually transiently transfected with large numbers (i.e., >100) of PD-L1 mutant-mCherry fusions.
  • systems usable with the methods include Perkin Elmer Cell::Explorer; a fully automated tissue culture-based liquid handler, a Janus workstation, Liconic shaking incubator, Envision plate reader - all accessible via a six-axis robotic arm contained within a BSL-2 biosafety hood to ensure sterility, for example.
  • Fully implemented automated tissue culture capabilities, including cell growth, media exchange, transfection, etc. aid efficiency.
  • the platform in multi-well format can, optionally , be benchmarked against the proven interaction pairs (PD-1:PD-L1, PD-1:PD-L2, PD-L1:B7-1, CTLA-4:B7, CD200R:CD200; Figures 4 , 6 , 10 , 11 ), as well as the entire panel of PD-L1 mutants ( Figure 12 ).
  • This can be extended to all members of the Ig Superfamily as described above and ultimately to the entire Secretome. It is important to note that while many labs have shown that cell-cell based interactions can readily be examined by FACS analysis ( Figures 10 and 11 ), these efforts are all of a low throughput nature and not easily ported to an exhaustive screen conferring the advantages as described here.
  • Another platform described herein employs magnetic capture techniques to rapidly enrich for cell-microbead (or cell-cell) conjugates formed as a consequence of specific receptor:ligand interactions[103] and massively parallel next-generation sequencing (e.g., Illumina/454[104-106]) to deconvolute the resulting pools (e.g., [107-110]).
  • next-generation sequencing e.g., Illumina/454[104-106]
  • This platform leverages a tagged expression vector for each member of the expression library, containing a unique nucleotide barcode (in the examples, 28 nucleotides, but other ranges may be used) that can be that can be amplified with "universal primers" and readily identified by deep sequencing ( Figure 13 ) [107-110].
  • the library of barcoded vectors can be pooled and transfected en masse into suspension-adapted HEK293 cells.
  • the pooled expression library is mixed with the query protein (in the context of microbead or cell surface presentation) to form conjugates, which are recovered by multi-well magnetic separation (performing, for example, 24 parallel separations in less than 30 minutes).
  • the magnetic query protein in the context of microbead or cell surface presentation
  • the barcodes from the enriched pool members are amplified and subjected to next-generation deep sequencing (e.g., up to 10,000,000 reads of 75 nucleotides each) to identify barcodes enriched by the capture process.
  • next-generation deep sequencing e.g., up to 10,000,000 reads of 75 nucleotides each
  • SPR, ITC, SEC, FACS in vitro biochemical approaches
  • each of the 500 members of the IgSF can be individually used as the query, with the captured conjugates from each query collected in a separate well of a multi-well plate.
  • This physical separation of candidate interactors for each query protein allows for "composite" primers to be used in the amplification step (i.e., each well receives a unique primer set in which the two "universal T7 priming sequences" are flanked by an additional 8 unique, well specific nucleotides).
  • composite primers allows for the specific identification of those library members (28 nucleotide core barcode) that are enriched due to interaction with the query protein corresponding to a particular well (additional well-specific nucleotide barcode, e.g.
  • Magnetic capture/enrichment The use of the Miltenyi system for cell enrichment in the context of cell-microbead conjugates is straightforward [103]. The use of 50 nm magnetic beads for cell enrichment is preferred but not limiting.
  • Figure 14 demonstrates use of magnetic microbeads to separate/enrich specific cell-cell conjugates that form as the consequence of cognate receptor:ligand interactions.
  • query proteins are expressed in a cell line stably expressing a transmembrane-anchored tag (e.g. FLAG) on the surface to allow capture by anti-FLAG bearing magnetic beads.
  • a transmembrane-anchored tag e.g. FLAG
  • microbead-bound capture reagent e.g., anti-FLAG
  • magnetic microbead capture allows for extensive washing steps and results in reduced background.
  • the strength of the very highly multivalent interactions associated with cell-cell conjugate formation is fully compatible with the relative gentle magnetic separation technology. This approach is not dependent on the measurement of fluorescent signals for determining "bound" and "unbound” events, and removes the complications of gating, laser settings etc.
  • Non-specific binding can occur between the query-expressing cell line and "off-targets" (i.e., cells not expressing a cognate ligand).
  • Figure 14B demonstrates the ability of the magnetic capture technology to specifically enrich for "rare events” (i.e., 1.5% of total possible interactions).
  • Figure 15 provides proof that the barcode approach is capable of detecting even more rare events. For typical binary cell-cell assays where the population is composed of a 1:1 mixture of cells expressing cognate receptor:ligand pairs (e.g., PD-1:PD-L1 and CD200:CD200R), 10-30% of events are typically scored as positive binding interactions (see Figures 10 and 11 ).
  • bound is defined as the number events that are both GFP and mCherry positive (i.e., Figure 15A , Quadrant 2).
  • the PCR-based validation of the enrichment of the PD-1 expressing cells is completely analogous to the barcoding strategy implemented to deconvolute the pooled amplicons (i.e., the PD-1 coding sequence acts as an intrinsic barcode).
  • the levels of enrichment achieved in Figures 14 and 15 are fully within the detection limits of the next-generation deep sequencing approaches being employed[113].
  • the PD-L1:PD-1 and PD-L1:B7-1 interactions can be examined with the unique barcode approach described in Figure 13 , as can the 500 genes belonging to the human IgSF incorporated into each of the two expression vectors (i.e., 500 receptors, 500 ligands) and subjected to interaction screening.
  • This system enables the concurrent query of many ligands against the entire panel of potential receptors, allowing for the simultaneous, efficient and cost effective interrogation of large query lists.
  • This approach can cover the entire Secretome.
